Vacuum Pump (Oil Rotary Vacuum Pump) Oil-sealed Rotary Vacuum Pump Components Division, ULVAC, Inc. Vacuum Pump The PVD series belt-drive oil rotary vane pumps are compact, quiet running and robust. The superior pumping performance of these industrial strength pumps has earned them an excellent reputation among many users. Applications • Vacuum drying and freeze drying • Vacuum packing, vacuum adsorption and transport • Gas substitution, filling and vacuum heat insulation • Vacuum casting, etc. VACUUM COMPONENTS Pumping Speed Curves L/min m3/h 500 30 400 Pumping Speed • Consistent Pumping Performance The pumping performance of the pump is extremely stable. • Low Vibration and Low Noise The pump is suitable for use in noise and vibration sensitive environments. • Easy Maintenance Because the pump body is machined from a single aluminum block casting the unit has fewer parts to maintain. • Gas-Ballast Valve Gas ballast valve is standard with these pumps to effectively deal with water vapor from condensation. • Oil-backflow Prevention This model contains an oil-backflow prevention device as standard equipment. • Various Options An optional base with casters allows ease of movement of the pump.

Components Division, ULVAC, Inc. Model *1 1 PVD-B series models (with oil back-flow prevention mechanism) are designated as PVD-180B for the PVD-180 model and PVD-360B for the PVD-360 models. 2 Measured with a Pirani gauge. 3 Please specify the need for a motor, the motor model, voltage, and power frequency when ordering. The fully sealed external fan motor, increased safety explosion-resistant motor, and pressure resistant explosion-resistant motor can also be ordered as options. (Except PVD-B series) 4 Other oil types are available, upon request. Note) Dimensions in () are forthe PVD-360 (B)...
